The Irritrol RD600-INT-R Rain Dial-R is a six-station indoor irrigation controller for residential sprinkler systems installed in a garage, utility room, basement, or other protected location. It provides familiar local programming with flexible schedules and support for optional Irritrol weather, remote-control, and connected-management accessories. This indoor model is not intended for direct outdoor exposure.
Three independent programs allow lawn, shrub, drip, or seasonal zones to use different watering days, start times, and station run times. Each program supports three daily start times for up to nine total starts. Station run time can be set from 1 to 59 minutes in one-minute increments or from 1.0 to 5.9 hours in six-minute increments. Water budgeting, monthly percentage presets, odd/even scheduling, skip-day intervals, excluded days, station delay, test-all-stations operation, and assignable pump/master-valve control help tailor the schedule to the property.
The controller is RainSensor-ready and supports optional Climate Logic weather sensing, SMRT Logic remote access, and CRR handheld remotes. These accessories are sold separately. A 9-volt alkaline battery, also not included, supports armchair programming and maintains time and date during a power interruption.
